For a Friedel-Crafts alkylation reaction between 1,4-dimethoxybenzene with 3-methyl-2-butanol and sulfuric acid what product was formed in this reaction? Use a discussion of the reaction mechanism, IR, and NMR data to justify your conclusion. A figure should be included to aid in the discussion of the reaction mechanism.

Question 30 (4 points) Friedel-Crafts alkylation reactions cannot be performed on benzaldehyde because: The aldehyde group is strongly activating, and multiple substitutions occur on the aromatic ring. The aldehyde group gets alkylated instead of the aromatic ring. The aldehyde group attacks the Lewis acid to form an acid-base complex in which the aromatic ring is strongly deactivated The aldehyde group is moderately deactivating preventing any substitution on the aromatic ring. Question 31 (4 points) Which of the following produces no...

Friedel-Crafts Acylation of Ferrocene "riedel-Crafts reactions are examples of electrophilic aromatic substitution reactions. The eaction involves the substitution of hydrogen on the aromatic ring system by an electrophilic arbon species forming a new carbon-carbon bond. Friedel-Crafts reactions may be used to ntroduce either an alkyl or acyl group. Ferrocene does not undergo addition reactions typical of cyclopentadiene, but undergoes Electrophilic aromatic substitution. The Friedel-Crafts acylation reaction of ferrocene involves he addition of the acylium cation to one of the carbon...

for the first picture i need to find out what the 2nd reaction
is (name of reaction). I have it as alpha alkylation but i’m not
sure if thats correct. I am unsure because while LDA is adding the
alkyl halide it is also adding an ester group along with it so I
did not know if that was possible with the alpha allylation.
In the second picture i need to know what the name of the
reaction the H+...

QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
